Scrooge (5)
I believe the answer is:
miser
'scrooge' is the definition.
(Dickens' Ebenezer Scrooge is a miser)
This is the entire clue.
(Other definitions for miser that I've seen before include "Hoarder of money and possessions" , "Curmudgeon" , "One of the people who spend least" , "auger" , "Stingy type" .)
